Hello aspirant,

Yes,a xerox copy is enough for Eamcet while councelling but make sure that you take the original certificate from your institute which you had completed your intermediate studies. It will be a mandatory document which you need to be produced to the college authority while reporting.It will be good for you to keep a set of xerox copies of all the documents and do upload in your personal gmail, no one knows when there will be a sudden requirement of a document.

Hope this helps
